EDWILL FISHER (1896-) American art circa 1930 pencil signed etching of figures in an interior by a hearth

Etching on paper, 10 1/2" by 13" and a narrow simple wood frame, the subject three generations of women by a 19th century style hearth in which a pot is boiling, the print signed in pencil at lower right by the artist EDWILL FISHER. I have looked extensively online and have found some other examples of his art, all graphic art, the subject matter including European scenes of castles and cities, and the American subjects including scenes on the Ohio River. Most the the works are dated 1930 and I'd suspect that might well be the approximate age of this print. I have been contacted by the daughter of the artist. She kindly provided the following biographical information on her dad: "EdWill Fisher was born 6/30/1896 in Rockport, Indiana and died 9/30/1960 in Minneapolis, MN. He grew up in Evansville, Indiana where he completed the fourth or fifth grade(?). I'm not sure how old my dad was when he came to MN. But, during the summer of 1909 he attended Bally Blake Camp for Boys, now Camp Lincoln, on the shores of Lake Hubert, MN. Bally Blake camp was run by EdWill's uncle and teacher, Wm. M. Blake. This is the same Wm. Blake that founded the well known Blake Schools in Minneapolis. EdWill was taught privately by his uncle but I don't believe he attended Blake School. In 1918 dad went off to WW1 where he became a cartographer. While in the service in France, dad studied with many French artists that were part of his company that produced maps. This is where he perfected his artistic skills. My dad also held a number of U. S. patents. In addition to his patent for the Fisher Flame lighter he also held patents for a color TV and colored photography process. Both the colored TV and colored photography patents were much ahead of their time! The majority of my dad's etching work was produced around 1930. The bulk of his etching work includes French scenes, Minnesota scenes, and Ohio River scenes. I have some of his watercolors of Clark Lake and Lake Hubert in MN. I also have additional etchings and some of his original copper plates. My hope is to catalog all dad's work." Note the vintage Chicago framing sticker.
